Gretchen, 32, joined the ranks of Miley Cirus, Kim Kardashian, Pamela Anderson and Lindsay Lohan when she created her own ‘Naughty Blonde Ambition‘ milkshake which includes Vanilla frozen yogurt, Reese’s Pieces, Heath Bar, Hersey’s Chocolate Syrup, Whipped Cream with a cherry on top. Gretchen created the shake with one thought in mind… “Naughty!”…In calories, that is.

Gretchen was also joined by Bravo’s Chad Rogers of Million Dollar Listing who came to support her. More photos of that below. In the meantime, check out the video of Gretchen as she shows us the proper way to down a milkshake. She also discusses Hollywood infidelities, her makeup line, her song and donating some of the proceeds to the Leukemia Foundation.
